Any of the M96's that I shot and worked on had twists around 1 in 7.6 or so. They liked heavier bullets and powders on the slow end of the scale e.g. IMR4350, IMR4831, H4831. Most of them absolutely loved the 160 grain Hornady round nose bullet and shot OK with 140's too. Some guys reported getting good accuracy with 120 grainers, but I never did. Of course, it's like any other reloading thing, you puts down your money and takes your chances. Oddly enough I don't think I ever shot one with the full length barrel. As I recall, I cut all the barrels down and recrowned them before shooting them. They were surprisingly accurate rifles in my experience. Sometimes I wonder about these older rifles now and how the steel in them is holding up. Feel the same way about P14-17's. Some of them are getting pretty long in the tooth. Fred
